The size of the InMail graphic on LinkedIn is an important consideration when creating engaging messaging and content for the platform. InMail is LinkedIn’s internal messaging system that allows users to contact other members directly without needing their email address or going through the general messaging system. Understanding the right InMail graphic size ensures your messages stand out in the recipient’s inbox and drive more opens and engagement.
The recommended size for InMail graphics on LinkedIn is 600×800 pixels. This allows the image to display properly across desktop and mobile experiences. Smaller graphics may appear blurry or pixelated, while larger sizes may get cropped or scaled down. The 600×800 pixel size hits the optimal balance between quality and performance.
InMail Graphic Display on Desktop
On the LinkedIn desktop experience, the InMail graphic displays prominently next to the preview text in the recipient’s message inbox. The graphic shows up as a 600×800 pixel image, filling most of the available messaging window space. This creates ample real estate for high-quality, eye-catching visuals to represent your brand and messaging.
Some key advantages of the 600×800 InMail graphic size on desktop include:
- Large enough to add branding elements, text, logos, and more
- Crisp, clear display without pixelation
- Grabs attention in the inbox preview
- Creates plenty of clickable space to drive opens
The large InMail graphics stand out in the inbox and give recipients a strong visual preview of your message content. This can help improve open rates compared to plain text-only previews.
InMail Graphic Display on Mobile
On mobile devices, the InMail graphic maintains the 600×800 pixel dimensions but displays adapted to the smaller screens. The graphic will span the entire width of the messaging window, giving it prominent visibility even on compact displays.
Key benefits of the 600×800 graphic size on mobile include:
- Spans the mobile inbox preview window width for high visibility
- Adapts seamlessly across varying mobile screen sizes
- Looks clean and professional, not awkwardly large or cropped
- Loads quickly and smoothly on mobile data connections
The 600 pixel width matches the mobile messaging window, while the 800 pixel height maintains the scale and prevents cropping or distortion. This keeps your InMail graphics looking great on any device.
Image Format Recommendations
When creating your 600×800 InMail graphics, JPEG or PNG file formats are recommended for the best results:
- JPEG – Ideal for photographs, more efficient compressed file size
- PNG – Better for logos, illustrations, text overlay, supports transparency
Avoid overly large uncompressed files like TIFF or BMP. Also steer clear of GIFs, since they may display incorrectly in the InMail preview.
Some tips for optimal InMail graphic files:
- Keep file sizes under 5MB
- Use 72 or 96 dpi resolution
- Save progressive JPEGs for faster loading
- Use PNG-24 format for high quality transparency
Following these best practices will help your 600×800 InMail graphics look polished and professional.
Ideal Image Content
When designing your InMail graphics, include content that will grab the recipient’s attention, communicate your key messaging, and inspire them to open your message. Some elements to consider:
- Logos and branding
- Photos or illustrations
- Text overlays
- Stats or data visualizations
- Promotions or offers
- Event details
Aim to make the graphic representative of your message content, while including eye-catching imagery and minimal text. This gives recipients enough preview to pique their interest without giving everything away up front.
